Design flaw dirty the result!

I have medium long, dark, wavy and thick hair unstruktriert. I am every day at least for 30 years. Half an hour busy they somehow form so that I can go among people ... advantage for years the GHD hair straighteners and I am very very happy with it. Now I wanted to bring a little more depth and momentum in the hair, because extremely smooth hair look boring in the long run. So I wanted to approach and tips screw something and have taken these extra large curling iron. In fact, he is like a flat iron, makes a little momentum to the peaks and on the approach. So whoever wants to have really curly or beautiful waves, take a narrower version.
It works, it soon becomes hot and the waves have the desired effect. Alas, it has been well developed by a man who has no idea how to use such a thing, because the very sensitive on / off button is located right where you hold curling iron. Ie. in 30 minutes, in which I doctored my hair so that I am at least. 20 come even think about it and the curling iron off unintentionally. It cools down quite quickly, that you wonder why nothing happens after 15-20 sec. Which should actually burned in the heat the hair and then you can see that it's from ... Well, actually is a tes great device with a variety of heat levels, nice design, etc. but for everyday life, it is simply useless. When I've tried my hand consciously by keeping the On / Off button away, I've twisted my arm and burned his finger.
It's obvious that this button has nothing to lose because where you have to hold the device!

I'll order the curling iron from Philipps and see if you have something further thought.
